Hello,
I can't understand why the turbine wake moves upwards.

The impacting air flow on the rotor always comes from the same direction (left), however, arrived at about 1 second of the simulation, the wake starts to move.
I attach two images to better understand the problem.

How can I solve it?
Thanks so much

PS: I'm new in the forum, can you attach .sim files? Because my file was rejected, even as a .zip extension.

Hello AlphaDelta
I think you have to check the boundary conditions.

Thanks.
Where could the wrong boundary conditions be? On the edge of the domain? At the interface between stationary and rotating regions?
